For reaching above-mentioned technique effect, the utility model adopts following technological scheme:
The multistage overlapping efficient wind energy generator set of a kind of upright shaft, comprise the main frame that is fixedly installed on the ground, it is characterized in that: described generator set is made of three overlapping generator units, connect by coupling between the generator unit, each generator unit comprises boss rod, be fixedly installed on blade on the boss rod, be located at the collection wind control system on the main frame, and described boss rod is connected with generator by speed increaser.
Described collection wind control system comprises wind collection guiding plate, air gathering plate support and guiding device, collection wind control-driven system.
Described boss rod is connected and composed by flexible connecting member by three axles, every axle is made of two spindle noses, hollow shaft and welded flanges, described spindle nose is fixedlyed connected with welded flange by hollow shaft respectively, and upper and lower axle is connected with jack shaft by flexible connecting member respectively.
Described blade windward side hollow indent, the smooth evagination of outlet air surface, its curvature of curved surface is along with increasing gradually away from running shaft.
Be connected by bolt between described boss rod and the blade.
Described collection wind control system is located on the main frame by bolt.
Described generator is the double-fed type generator.
Be provided with steel cable between ground and the main frame.
The utility model utilization collection wind and wind-force guiding principle make the stress surface of wind force power machine fan blade and wind direction right angle each other, wind-force direct projection, directly pushing generator fan blade along continuous straight runs rotation.Therefore wind direction can not produce eddy current down, and the blower fan spacing can reduce.In order to increase the collection air quantity, improve wind-force, increase wind force power machine speed and power, the multistage overlapping efficient wind energy generator set of upright shaft has increased the air gathering plate system, regulates the air gathering plate angle, can control the air quantity that is subjected to of wind force power machine, regulates the rotating speed of motor.When wind speed surpasses last prescribing a time limit,, make wind force power machine be in state of equilibrium all the time by regulating the air quantity that is subjected to that the air gathering plate folding changes wind force power machine.Regulate air gathering plate and can make the wind-driven generator work wind speed of falling the maximum functional, when wind speed exceeded the maximum functional wind speed, air gathering plate was closed fully, and wind-driven generator quits work, and plays the effect of protection generator system.Be located at steel cable between ground and the main frame, in order to strengthen the steadiness of discharge unit.
This wind energy power unit Applicable scope is extremely wide.Compare with the three oar blade type wind-driven generators that generally adopt both at home and abroad, this machine height only is 1/3 of its height, the rotational speed height, balance is better, does not need pylon and the steering gear, noise free, can be placed on the high-rise of town and country, be convenient to generate electricity by way of merging two or more grid systems with electrical network and other power equipment.The utility model is simple in structure, cost is low, the installation cycle is short, to the applied widely of wind field and to Wind Power Utilization thoroughly, generating is effective, be suitable for applying.
